Part of our Aeroslim overview. Last checked October 28, 2026.
Aeroslim supplements side effects have not been studied in the product itself, but its label ingredients carry known cautions, and the biggest is liver risk from coltsfoot.[1] Coltsfoot contains pyrrolizidine alkaloids (PAs), and a systematic review collected 11 case reports linking coltsfoot or comfrey to PA harm.[3] The blend's 500 mg total hides every dose, so nobody outside the maker knows how much coltsfoot a tablet holds.
Is Aeroslim safe? Safety at a glance
We cannot call it safe for everyone, because the biggest concern cannot be measured from the label. Coltsfoot's PAs can cause hepatic veno-occlusive disease, a blockage of small veins in the liver, and the label neither gives a dose nor says the extract is PA-tested.[3] Umckaloabo, also in the blend, has a European Medicines Agency (EMA) warning about liver injury, which means two liver-flagged herbs in one tablet.
On the plus side, an FDA adverse event database search found no records for "aeroslim" when we checked on October 28, 2026, and no recalls were listed. That does not prove safety; it means nothing was reported there. The label itself tells pregnant or nursing women, anyone under 18 and anyone with a medical condition to ask a physician first.[1]
What side effects are possible?
Expected side effects come from the individual ingredients, since Aeroslim has no trial of its own. They fall into three groups.
Digestive
The EMA lists nausea, vomiting and diarrhea for ivy leaf, and stomach upset for umckaloabo. NCCIH notes peppermint oil can cause heartburn, nausea, abdominal pain and dry mouth.[9] Ivy also calls for caution if you have gastritis or a stomach ulcer.
Allergy and sensitivity
Ivy can cause hives, rash and, rarely, breathing difficulty or anaphylaxis, so avoid it if you react to plants in the ivy family. Umckaloabo lists rash and hypersensitivity, and peppermint oil has rare allergy reports.
Medicine-related and bleeding
Umckaloabo lists nosebleeds and gum bleeding as possible effects. Serratiopeptidase has fibrinolytic activity, which means it breaks down the protein that holds clots together.[8] Its long-term safety has not been established.[7]
Which ingredients deserve extra attention?
Four ingredients carry the clearest cautions, based on the label and our evidence notes read October 28, 2026. The common thread is that no dose is disclosed for any of them.
| Ingredient | Safety issue | Why it matters |
|---|---|---|
| Coltsfoot (flower) | Pyrrolizidine alkaloids such as senkirkine and senecionine | Can damage the liver; PA testing not stated; no human trial exists |
| Umckaloabo (root) | EMA lists hepatotoxicity and hepatitis, frequency unknown | Second liver-flagged herb in the same blend |
| Serratiopeptidase | Breaks down fibrin; long-term safety unknown | Caution with blood thinners and before surgery |
| Ivy leaf | Stomach upset, allergic reactions | Caution with gastritis, ulcer or ivy-family allergy |
| Xylitol (other ingredient) | Raised platelet reactivity in one study; toxic to dogs | Worth a mention for people on clot medicines; keep away from pets |
The PAs in coltsfoot have been measured in the plant itself.[5] The best-known case of liver injury, an infant with reversible veno-occlusive disease, involved a tea sold as coltsfoot that turned out to be a look-alike PA plant.[4] For umckaloabo, a causality review of 13 suspected liver cases confirmed none, so its liver risk looks lower than coltsfoot's.[6] Xylitol's platelet finding comes from a cohort and an intervention study.[10] More on each herb is in our Aeroslim ingredients guide.
Which medicines could interact?
No drug interaction study exists for Aeroslim, so the groups below are precautions based on how the ingredients work. Take this list to a pharmacist before you start.
- Blood thinners: anticoagulants such as warfarin and antiplatelet drugs such as clopidogrel or daily aspirin. Serratiopeptidase breaks down fibrin, and umckaloabo lists bleeding-type effects.
- Upcoming surgery or dental work: tell your surgeon or dentist, for the same reason.
- Anything hard on the liver: alcohol, other herbs with PAs and other products containing umckaloabo.
- Drugs or herbs that speed up liver enzymes: PAs are activated in the liver, so in theory these could raise toxicity. This is a mechanism, not a documented interaction.
- Other vitamin D products: Aeroslim adds 20 mcg (800 IU); the adult upper limit is 4,000 IU (100 mcg) a day.
Pregnancy, breastfeeding and who should ask a doctor first
Avoid Aeroslim during pregnancy and breastfeeding. Coltsfoot should be avoided in both, and the EMA does not recommend umckaloabo or ivy without safety data. Ask a doctor before starting if you:
- are pregnant or breastfeeding
- are under 18 (the label says so, though the FAQ claims it suits all ages)[2]
- have liver disease, raised liver enzymes or drink heavily
- take a blood thinner or have a bleeding disorder
- have surgery planned within the next few weeks
- have gastritis, a stomach ulcer or an ivy-family allergy
- take any prescription medicine every day
Which symptoms need a doctor right away?
Stop taking Aeroslim and get medical help right away if you notice any of these:
- yellow skin or eyes, dark urine or pale stools
- pain or swelling in the upper right belly, or a swelling belly
- unusual tiredness with nausea or loss of appetite
- unusual bruising, nosebleeds, bleeding gums or blood in urine or stool
- hives, swelling of the face, lips or tongue
- trouble breathing or a tight throat: call 911
- vomiting or diarrhea that lasts more than a day
Bring the bottle so the doctor can read the label.
Safety conclusion
Aeroslim is not a product to take casually. Coltsfoot brings a liver risk that the label does not address, umckaloabo adds a second liver warning, and serratiopeptidase needs a check if you take blood thinners. The milder effects listed for its herbs are stomach upset and allergy, but without a trial or disclosed doses nobody can say how often they happen. If you decide to try it, clear it with your doctor first and follow the directions on how to take Aeroslim.

Frequently asked questions
Can Aeroslim hurt your liver?
It might. Coltsfoot in the blend contains pyrrolizidine alkaloids that can damage the liver, and umckaloabo carries an EMA liver warning. The dose of each is hidden and PA testing is not stated, so people with liver problems should avoid Aeroslim.
Can I take Aeroslim with blood thinners?
Ask your doctor or pharmacist first. Serratiopeptidase breaks down fibrin, the protein in clots, and umckaloabo lists nosebleeds and gum bleeding. No interaction study exists, so this is a precaution based on how the ingredients work.
Can Aeroslim upset your stomach?
Yes, that is the most likely mild effect. Ivy leaf can cause nausea, vomiting and diarrhea, and peppermint oil can cause heartburn and abdominal pain. Stop and see a doctor if vomiting or diarrhea lasts more than a day.
Is Aeroslim safe while pregnant or breastfeeding?
We advise against it. Coltsfoot should be avoided in pregnancy and breastfeeding, and the EMA does not recommend umckaloabo or ivy without safety data. The Aeroslim label itself tells pregnant and nursing mothers to consult a physician.
Have any Aeroslim side effects been reported to the FDA?
When we searched the FDA adverse event database on October 28, 2026, it had no records for aeroslim, and no recalls were listed. An empty database does not prove a product is safe; many reactions go unreported.
